Description

Technical Field

[0001] This application relates to the field of enterprise production information management technology, and in particular to a BOM and CAD verification method, device, computer equipment and storage medium. Background Technology

[0002] With the rapid development of the automotive industry, the R&D requirements for powertrains (engines / transmissions) are becoming increasingly stringent. During the R&D process, product prototyping of the developed solutions is necessary. The condition of the prototype during prototyping determines whether interference or misassembly will occur during actual assembly. The prototype BOM (Bill of Material) and prototype CAD (Computer-Aided Design) data are the fundamental data reflecting the prototype's condition. Furthermore, by verifying the data in the prototype BOM and prototype CAD, the data quality can be improved, further enhancing the prototype's condition. Therefore, how to verify the data in the prototype BOM and prototype CAD and improve their data quality is a key research focus in this field.

[0003] Currently, the commonly used verification method is manual operation, which involves manually checking offline to find problems and then making further modifications.

[0004] However, the manual operation method in the above technical solutions increases the communication cost significantly, and the quality of the verified data is not high, the system is not highly systematic, and the efficiency of data verification is reduced. Summary of the Invention

[0005] This application provides a BOM and CAD verification method, apparatus, computer equipment, and storage medium for systematically verifying BOM and CAD data during the prototype manufacturing process, thereby improving the efficiency of data verification. The technical solution is as follows:

[0006] On the one hand, a method for BOM and CAD verification is provided, which includes:

[0007] Obtain the prototype BOM and prototype CAD of the test assembly. The prototype BOM is used to describe the part information of multiple prototype parts in a test assembly. Each prototype CAD is used to simulate the configuration result of a test assembly. The part information includes part number and part location.

[0008] Based on the part names of multiple prototype parts indicated in the prototype BOM, obtain the part structure diagrams of multiple prototype parts.

[0009] Based on the part positions of multiple prototype parts indicated by the prototype BOM and the part structure diagrams of multiple prototype parts, the corresponding positions in the prototype CAD are identified respectively. If an element matching the part structure diagram is identified at the position, the character recognition is performed on the surrounding area of ​​the element to obtain the part number of the element.

[0010] If it is determined that the part numbers of multiple identified elements are the same as the corresponding part numbers in the prototype BOM, then a verification pass message is output, indicating that the prototype BOM and prototype CAD of the prototype system are matched.

[0011] On the other hand, a BOM and CAD verification device is provided, the device comprising:

[0027] In some embodiments, the data acquisition module is used for at least one of the following:

[0055] Figure 2 This is a flowchart of a BOM and CAD verification method according to an embodiment of this application, such as... Figure 2 As shown, this application uses a computer device as an example for illustration. The method includes the following steps:

[0056] 201. The computer equipment acquires the prototype BOM and prototype CAD of the test assembly. The prototype BOM is used to describe the part information of multiple prototype parts in a test assembly. Each prototype CAD is used to simulate the configuration result of a test assembly. The part information includes part number and part location.

[0057] In some embodiments, the computer device obtains a prototype BOM list and a prototype CAD from the server. The prototype BOM list includes multiple prototype BOMs. In addition to the part information of multiple prototype parts in the aforementioned prototype assembly, the prototype BOMs also include header information such as assembly number, internal name, project code, project name, configuration information, configuration description, purpose, and prototype time of the prototype assembly. The content of the header information for each prototype BOM is independent. The prototype CAD displays a three-dimensional model of the prototype assembly, which simulates the configuration result after the final assembly of the prototype assembly.

[0058] The prototype BOM and prototype CAD are constructed by the DRE (Design Release Engineer). The DRE edits the content corresponding to the header information in the prototype BOM by referencing data in the EBOM (Engineering Bill of Material). During the editing process, a mode of batch editing multiple prototype powertrains is adopted, editing the data in the EBOM of the same batch of powertrains in the same line of the prototype BOM. The prototype status of each prototype powertrain is recorded by marking the end of each prototype powertrain. The DRE creates the prototype CAD based on the part structure drawings of multiple prototype parts in the prototype powertrain and describes the purpose of the prototype CAD for prototype parts. For example, in the engine reliability verification test, the purpose of the prototype part is described as demonstrating the state of the part under extreme conditions. Therefore, the purpose of the prototype CAD is described as being used to verify engine reliability under extreme conditions.

[0059] There are multiple correspondences between the trial production assembly, the trial production BOM, and the trial production CAD. These multiple correspondences reflect various trial production scenarios, which are determined based on actual business needs.

[0060] In some embodiments, the correspondence is that one test brake assembly corresponds to one prototype BOM and one prototype CAD. In this case, only one test brake assembly is manufactured in a batch of prototypes, and the prototype CAD corresponding to the test brake assembly has only one usage description, that is, the test brake assembly corresponding to the prototype CAD is only used for one type of test, and thus corresponds to only one prototype BOM, which includes the test data of that type of test. In other embodiments, the correspondence is that one batch of test brake assemblies corresponds to multiple prototype BOMs and one prototype CAD. In this case, multiple test brake assemblies are manufactured in a batch of tests. Since the configuration results of the multiple test brake assemblies are the same, the multiple test brake assemblies correspond to one prototype CAD, but the usage description of the one prototype CAD is multiple, that is, the test brake assembly corresponding to the prototype CAD is used for multiple different types of tests, thus corresponding to multiple prototype BOMs, and each prototype BOM corresponds to the multiple different types of tests, including the test data of the multiple different types of tests.

[0061] 202. The computer equipment obtains the part structure diagrams of multiple prototype parts based on the part names indicated in the prototype BOM.

[0062] The part structure drawing includes three views of the prototype part, namely the front view, side view, and top view. Each part structure drawing also includes complete dimensions, a title block, and dimension annotations. The complete dimensions are used to determine the size and position of each part of the prototype part. The title block includes the part name, part material, and part structure drawing number of the prototype part, which is used to describe the basic information of each part structure drawing. The dimension annotations are used to indicate the actual size and relative position of the prototype part.

[0063] In some embodiments, when querying different part structure diagrams, the part name in the title bar is used as the query condition to obtain the corresponding part structure diagram, and then subsequent identification is performed based on the three views of the part structure diagram.

[0064] 203. The computer equipment identifies the corresponding positions in the prototype CAD based on the part positions and part structure drawings of the multiple prototype parts indicated by the prototype BOM. If an element matching the part structure drawing is identified at the position, the character recognition is performed on the surrounding area of ​​the element to obtain the part number of the element.

[0065] The prototype CAD includes a three-dimensional model and three views corresponding to the three-dimensional model. Based on the three views corresponding to the three-dimensional model, the recognition process is completed at the corresponding position in the prototype CAD.

[0066] For example, first, the positions of the multiple prototype parts are determined in the prototype BOM. Based on the positions of the parts, the corresponding positions of the three views in the prototype CAD are determined. These corresponding positions are the positions for identification. The three views of the corresponding positions are obtained. Then, the three views of the corresponding positions are compared with the three views of the multiple part structure drawings to determine whether there are matching elements.

[0067] The element that matches the part structure diagram is the shape or outline of the part. If the shape or outline is the same, it means that the part at the corresponding position is consistent with the part type indicated in the prototype BOM, and then the next step of character recognition is performed.

[0068] In the three-dimensional model, the positions corresponding to multiple prototype parts are marked with part numbers. Based on the part number, the prototype part to be installed at that position is determined. In this embodiment, after identifying the element that matches the part structure diagram at the corresponding position, the part number at the corresponding position can be determined based on character recognition, thereby determining the prototype part to be installed at the corresponding position.

[0069] In some embodiments, the recognition process is based on image recognition functionality. Image features are extracted from the three views corresponding to the 3D model and the three views corresponding to the part structure diagram to obtain image data of the three views corresponding to the 3D model and the three views corresponding to the part structure diagram, respectively. The image data includes the shape, color, and texture of the image. Then, matching elements are determined by comparing the respective image data. If the image data of the three views corresponding to the 3D model and the image data of the three views corresponding to the part structure diagram have the same part, then the element corresponding to the same part in the three views corresponding to the 3D model is the element that matches the part structure diagram.

[0070] 204. If it is determined that the part numbers of multiple identified elements are the same as the corresponding part numbers in the prototype BOM, the computer equipment will output a verification pass message, which indicates that the prototype BOM and prototype CAD of the prototype system are matched.

[0071] The character recognition process is repeated multiple times, and each of these multiple character recognition processes corresponds to a different element that matches the part structure drawing.

[0072] In some embodiments, if the part numbers of the surrounding areas of different elements obtained based on character recognition are consistent with the part numbers in the prototype BOM, it indicates that the prototype CAD and the prototype BOM contain the same prototype parts, and the installation positions indicated by the prototype parts are also consistent. In this case, the prototype BOM matches the prototype CAD, and the prototype BOM can be used in the actual product prototyping process.

[0073] In some embodiments, if a mismatched part number is identified, it indicates that there is a difference between the prototype BOM and the prototype CAD, and a verification failure message is output. The verification failure message indicates that the prototype BOM and the prototype CAD of the prototype system do not match, which means that the prototype BOM or the prototype CAD needs to be checked, the problem needs to be identified and resolved. The verification failure message includes the identified different part numbers or different numbers of parts corresponding to the same part number.

[0074] In some embodiments, the verification process described in steps 201 to 204 above can also be applied to the verification of the modified parts list, which also includes multiple modified BOMs and modified CADs. The modified parts list is used for the production of the modified mode before the completion of the three-dimensional model of the power unit. In this modified mode, the modified BOM of the power unit needs to be based on the existing BOM, which is the BOM that needs to be modified. Therefore, the modified BOM created includes the data of the basic physical power unit and the data of the target modified power unit. The data of the target modified power unit is the data of the power unit to be modified in the plan. The verification process of the modified BOM and the modified CAD is the same as that in steps 201 to 204 above.

[0075] The method provided in this application can obtain the prototype BOM and prototype CAD of the prototype manufacturing process, and use them to verify the prototype BOM and prototype CAD. Then, based on the part names of multiple prototype parts in the prototype BOM, the part structure diagrams of the multiple prototype parts are obtained to prepare for the subsequent identification process. Based on the part structure diagrams and the part positions of the multiple prototype parts in the prototype BOM, identification is performed in the prototype CAD to identify multiple elements that match the part structure diagrams and further identify multiple part numbers of these multiple elements. If the multiple part numbers are all the same as the part numbers in the prototype BOM, it indicates that the prototype BOM and prototype CAD match, and the verification pass information is output. This method realizes the verification of the prototype BOM and prototype CAD through a systematic approach and image recognition, eliminating the need for manual offline verification, improving the accuracy of the verification results and the quality of the verified data, thereby improving the efficiency of data verification.

[0076] The above Figure 2 The illustrated embodiment is a brief description of BOM and CAD verification methods. Below, based on... Figure 3 The illustrated embodiment further illustrates this technical solution. Figure 3 This is a flowchart of a BOM and CAD verification method according to an embodiment of this application, such as... Figure 3 As shown, this application uses a computer device as an example for illustration. The BOM and CAD verification method includes the following steps:

[0077] 301. The computer equipment acquires the configuration information of the overall trial production BOM and trial production CAD. The configuration information includes the architecture information and part information. The part information includes the part function and part location.

[0078] The configuration information indicates the configuration of the trial assembly corresponding to the prototype BOM and the prototype CAD, the architecture information indicates the overall framework of the trial assembly, the part function indicates the specific purpose of multiple prototype parts in the trial assembly, and the part position indicates the specific configuration position of the multiple prototype parts in the trial assembly. Each prototype BOM and prototype CAD has a corresponding configuration information, and based on the configuration information, the trial assembly corresponding to the prototype BOM and the prototype CAD can be determined.

[0079] 302. The computer equipment obtains the configuration information of the test brake assembly from the configuration information table. Based on the configuration information of the test brake assembly, it verifies the prototype BOM and prototype CAD. If the configuration information of the prototype BOM and prototype CAD is consistent with the configuration information of the test brake assembly, it outputs the verification pass information. The verification pass information indicates that the prototype BOM and prototype CAD correspond to the same test brake assembly.

[0080] The configuration information table includes configuration information for multiple test brake systems. Based on the system number of each test brake system, these multiple test brake systems are classified, and the configuration information corresponding to test brake systems with different system numbers is different. Therefore, the system number is arranged based on the system configuration information. For example, the system number is arranged in ascending order according to the number of parts included in the test brake system, or the system number is arranged in alphabetical order according to the name of the most frequently used material in the test brake system, thereby realizing the classification of multiple test brake systems.

[0081] In some embodiments, based on the power assembly number, the configuration information of the test power assembly is obtained. The architecture information in the configuration information of the test power assembly is compared with the architecture information in the configuration information corresponding to the prototype BOM. If the architecture information is the same, the part information in the configuration information of the test power assembly is compared with the part information in the configuration information corresponding to the prototype BOM. If the part information is the same, it means that the prototype BOM corresponds to the test power assembly. If the architecture information is different, or if the architecture information is the same but the part information is different, it means that the prototype BOM does not correspond to the test power assembly.

[0082] The process for determining whether the prototype CAD corresponds to the prototype brake assembly is the same as the process for determining whether the prototype BOM corresponds to the prototype brake assembly.

[0083] The verification information is used to determine whether the prototype BOM and prototype CAD belong to the same group, that is, whether the prototype BOM and prototype CAD correspond to the same prototype assembly. Only prototype BOMs and prototype CADs in the same group can be verified to determine whether the prototype BOM and prototype CAD match.

[0084] 303. The computer equipment acquires the prototype BOM and prototype CAD of the test assembly. The prototype BOM is used to describe the part information of multiple prototype parts in a test assembly. Each prototype CAD is used to simulate the configuration result of a test assembly. The part information includes part number and part location.

[0085] In some embodiments, the acquired trial production BOM and trial production CAD are managed through different systems, namely a trial production BOM management system and a trial production CAD management system. The trial production BOM management system can provide rich data reporting tools to meet the data analysis needs of various departments. The data analyzed includes historical trial production BOM data and the latest trial production BOM data. Furthermore, when performing data analysis, data sources from other systems within the enterprise, such as the trial production CAD management system, can also be referenced to enrich the data analysis capabilities and ensure that the departments applying the trial production BOM data can obtain data in real time and efficiently and respond quickly to business needs, thereby improving the efficiency of data analysis.

[0086] The prototype CAD management system provides model storage and editing functions. For example, the 3D model corresponding to the prototype CAD can be created in the PDM (Product Data Management) system. By integrating PDM with CAD, more detailed information about the 3D model can be obtained. Furthermore, the PDM can record and store data related to the CAD creation and modification processes, achieving data traceability and clarifying the responsibilities of professional reviewers.

[0087] In some embodiments, the operation of obtaining the prototype BOM and prototype CAD for the overall trial production is based on different triggering conditions, which are also the triggering conditions for verifying the prototype BOM and prototype CAD. These triggering conditions include the following 303A and 303B:

[0088] 303A: Obtain the overall prototype BOM and prototype CAD for prototypes whose release date is before the target date and the number of days between them is greater than the target date.

[0089] The actual trial production process is based on the final released trial production BOM. The final released trial production BOM determines whether problems will occur during the actual trial production process. Therefore, before the final release, the trial production BOM and trial production CAD need to be verified to ensure that the trial production BOM is free of problems or to identify and resolve problems in advance.

[0090] In some embodiments, the target number of days is 5 to 10 days, which ensures that there is sufficient time to identify and resolve problems, thereby guaranteeing the normal release of the prototype BOM and prototype CAD.

[0091] 303B: Obtain the revised prototype BOM and prototype CAD for the overall test run, and change it based on the issues found in the previous verification.

[0092] In some embodiments, if the verification reveals a mismatch between the prototype BOM and the prototype CAD, the prototype BOM or prototype CAD is modified after analysis to determine the problem. After the modification is completed, the verification is performed again to ensure that the modified prototype BOM and prototype CAD can pass the verification.

[0093] There are various reasons why the prototype BOM and prototype CAD might not match, and different solutions exist for different problems. In some embodiments, an editing error occurs during the DRE's editing of the prototype BOM, even though the prototype CAD meets the prototype requirements. In such cases, the content in the prototype BOM needs to be modified to match the prototype CAD. In other embodiments, after the prototype BOM is initially released, the DRE submits a change request. After the change request is approved by the general layout engineer, professional manager, project director, and other relevant personnel, the DRE modifies the initial version of the prototype BOM and re-releases it. However, the prototype CAD corresponding to this prototype BOM remains unchanged and is still in its initial version state. In this case, the content in the prototype CAD needs to be modified to match the re-released prototype BOM.

[0094] In some embodiments, the change request includes an upgrade change request and a non-upgrade change request. The upgrade change request indicates that the prototype BOM to be changed is already a complete version. The complete version indicates that the content of the prototype BOM includes all the content edited by different DREs and the content supplemented by the prototype department personnel. The supplemented content includes record information related to prototype production, such as material requisition locations, sample locations, and prototype workshop workstations. The material requisition location is used to indicate the location of the material to be requisitioned, and the sample location is used to indicate the location of the sample material. The non-upgrade change request indicates that the prototype BOM to be changed is not a complete version and only includes part of the content edited by DREs.

[0095] The release of the full version of the prototype BOM requires a corresponding system process. This process includes obtaining multiple prototype BOMs released by multiple Design Engineers (DREs), summarizing these multiple prototype BOMs to obtain the full version of the prototype BOM, and having the prototype BOM engineer organize relevant personnel such as the test manager and project manager to conduct an offline review of the prototype BOM content. This offline review includes determining whether the prototype BOM content meets the Design Verification Plan (DVP). If it meets the DVP, the prototype BOM engineer releases the full version of the prototype BOM.

[0096] 304. Based on the part names of multiple prototype parts indicated in the prototype BOM, the computer equipment obtains the part structure diagrams of multiple prototype parts.

[0097] Each prototype part corresponds to one or more part structure diagrams. These multiple part structure diagrams have the same part name but different part structure diagram numbers. They are divided according to the different parts described in the prototype part. Therefore, based on the part name of a prototype part, one or more part structure diagrams can be obtained. If only one part structure diagram is found, it means that the part structure diagram corresponds to a part of the entire prototype part. If multiple part structure diagrams are found, it means that the multiple part structure diagrams correspond to different parts of the prototype part. This further refines the structure of the prototype part, making the subsequent identification results more accurate.

[0098] 305. The computer equipment identifies the corresponding positions in the prototype CAD based on the part positions and part structure drawings of multiple prototype parts indicated by the prototype BOM. If an element matching the part structure drawing is identified at the position, the surrounding area of ​​the element is identified to obtain the part number of the element.

[0099] In some embodiments, since the dimensions in the three-view drawings differ from the actual dimensions, it is necessary to first perform scale mapping to identify the corresponding positions in the part structure drawing and the prototype CAD. This identification process includes the following steps 305A-305C:

[0100] 305A: Obtain the drawing scale of the prototype CAD, which indicates the scale used in the prototype CAD.

[0101] The drawing scale can be represented in various ways, such as numerical, segment-length, and textual formats. Based on the three views corresponding to the three-dimensional model in the prototype CAD, the drawing scale of the prototype CAD can be obtained.

[0102] In some embodiments, different drawing methods for the prototype CAD have different drawing scales, and this application does not limit this.

[0103] 305B: Based on the part positions and drawing scales of multiple prototype parts indicated by the prototype BOM, the theoretical positions of multiple prototype parts in the prototype CAD are obtained.

[0104] Specifically, based on the drawing scale of the prototype CAD, the data corresponding to the part positions of multiple prototype parts indicated in the prototype BOM are converted, and the converted part positions are the theoretical positions of the multiple prototype parts in the prototype CAD.

[0105] Based on this theoretical position, the position corresponding to the part structure drawing in the prototype CAD can be accurately located.

[0106] 305C: Identify multiple prototype parts located at their theoretical positions in the prototype CAD drawing, based on their theoretical positions.

[0107] The identification process is repeated and continuous for different theoretical positions. Each identification process targets a different theoretical position. When identifying any prototype part, the size of the part structure diagram of the prototype part is used as a window within a certain range centered on the theoretical position. Each time the window is slid, the part structure diagram is matched with the image block in the window. When the match is successful, it can be determined that the prototype part exists at that position.

[0108] In some embodiments, the identification process includes: matching the part structure diagram of the prototype part with a plurality of prototype parts located within a square with a preset side length, centered on the theoretical location.

[0109] The square is the sliding window mentioned above. The size of the window remains unchanged. Based on the change of the theoretical position, the window slides in the three views corresponding to the prototype CAD 3D model. Each time, only the elements in the window are identified. Image features of the elements in the window are extracted and matched with the part structure drawing. After obtaining the elements that match the part structure drawing, the part number of the element is identified.

[0110] 306. If it is determined that the part numbers of multiple identified elements are the same as the corresponding part numbers in the prototype BOM, the computer equipment will output a verification pass message, which indicates that the prototype BOM and prototype CAD of the prototype system are matched.

[0111] In some embodiments, the matching between the prototype BOM and the prototype CAD can also be determined using architectural information, wherein the method includes the following steps 306A and 306B:

[0112] 306A: Obtain the architectural information of the prototype BOM of the test brake assembly. The architectural information includes the overall dimensions of the test brake assembly. Based on the architectural information, identify the test brake assembly simulated in the prototype CAD.

[0113] The architecture information is obtained from the configuration information of the prototype BOM. The overall dimensions of the architecture information include the length, width, height and diameter of the prototype prototype. Based on this data, the external shape of the prototype prototype can be determined. The external shape of the prototype prototype can reflect the characteristics of the prototype prototype. Therefore, based on the architecture information, it is also possible to determine whether the prototype BOM matches the prototype CAD.

[0114] 306B: If it is determined that the overall dimensions of the prototype brake assembly simulated in the identified prototype CAD are the same as the architecture information, then a verification pass message is output, indicating that the prototype brake assembly's prototype BOM and prototype CAD match.

[0115] The overall dimensions of the test assembly simulated in the prototype CAD can be obtained based on the configuration information of the prototype CAD. If the overall dimensions are the same as the architecture information of the prototype BOM indicated in step 306B above, it can also be said that the prototype BOM and the prototype CAD correspond to the same test assembly, and therefore the verification pass information is output.

[0116] In some embodiments, the overall dimensions of the prototype assembly vary depending on the scale of the prototype CAD application, while the data in the architecture information of the prototype BOM is fixed. Therefore, when making comparisons, it is necessary to change the scale of the overall dimensions of the prototype assembly according to the data in the architecture information so that the overall dimensions are the same as the scale of the data in the architecture information, thereby making the comparison more accurate.

[0117] The method provided in this application first determines the prototype BOM and prototype CAD corresponding to the same test assembly based on configuration information. Then, it obtains the prototype BOM and prototype CAD of the test assembly for verification. Next, based on the part names of multiple prototype parts in the prototype BOM, it obtains the part structure diagrams of these multiple prototype parts to prepare for subsequent identification. Based on the part structure diagrams and the part positions of the multiple prototype parts in the prototype BOM, it identifies them in the prototype CAD. Multiple elements matching the part structure diagrams are identified by drawing scale in the CAD, and further, multiple part numbers of these elements are obtained. Compared to manual offline verification, this significantly shortens the verification time. If the multiple part numbers are all the same as the part numbers in the prototype BOM, it indicates that the prototype BOM and prototype CAD match, and verification pass information is output. This method achieves verification of the prototype BOM and prototype CAD through a systematic approach and image recognition, eliminating the need for manual offline verification, improving the accuracy of the verification results and the quality of the verified data, thereby improving the efficiency of data verification.
